I am not a photo or any kind of camera snob, but I have had years of turning out pictures on my two Incredibles that my wife (who actually is a professional photographer) was impressed with. When I changed to my Razr M, I have months of pictures that many I won't even show her. They are DEFINITELY not as good.
The picture someone posted above is outside, of stills.. I have found it reasonably good outside and for still environments. In any kind of indoors, and with motion (people), it seems to really struggle to focus correctly, and the resulting picture is frequently out of focus and/or blurry because it took to long and people moved, and frequently off color (although that less than the focusing issue). So in a party environment, I find it very frustrating.
Feel free to disregard my opinion, as it of course is an opinion, but please don't say that I formed it only from reading a review when I actually have hundreds of examples of empirical evidence. I had NEVER looked for a camera app replacement for my Incredibles; they took great pictures. This last week, after a NYE party, is the second time I have tried to "fix" my camera's abilities and went for a third party app. I didn't notice much difference the first time, so went back to stock; but again this holiday, I got so frustrated by the camera missing shots that I never would have missed with my old phone that I tried again.
It's too early to tell if this time it will help at all. It isn't clear to me (no pun intended), but seems like it might help slightly in taking pictures a little faster, so I can get a picture before everyone moves; but it still seems to be out of focus or something. I don't know, I just know they don't look nearly as good as the old phone's pictures; and by someone that isn't overly particular and not a professional photographer, that says it is noticeable.
That being said, you are trying to use it for Macro pictures, which I have never used it for, and under good lighting, stills using the macro setting might be fantastic! So take this only as a comment in the conditions described.
